Releases o Ubuntu 20.04 LTS Packages o linux-oem-5.14 - Linux kernel for OEM systems Details Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM implementation in the Linux kernel did not properly perform guest page table updates in some situations. An attacker in a guest vm could possibly use this to crash the host OS. ( CVE-2022-1158 ) It was discovered that the implementation of X.25 network protocols in the Linux kernel did not terminate link layer sessions properly. A local attacker could possibly use this to cause a denial of service (system crash). ( CVE-2022-1516 ) It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). ( CVE-2022-28388 ) It was discovered that the Microchip CAN BUS Analyzer interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). ( CVE-2022-28389 ) It was discovered that the EMS CAN/USB interface implementation in the Linux kernel contained a double-free vulnerability when handling certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). ( CVE-2022-28390 ) Update instructions The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 o linux-image-5.14.0-1036-oem - 5.14.0-1036.40 o linux-image-oem-20.04c - 5.14.0.1036.33 o linux-image-oem-20.04b - 5.14.0.1036.33 o linux-image-oem-20.04d - 5.14.0.1036.33 o linux-image-oem-20.04 - 5.14.0.1036.33 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
